Abstract

Electrical conductivity is an important property of electroless nickel plated fabric. The optimized electroless nickel plating method can provide useful information for textile industries to obtain optimum surface resistance and stable plating. In this study, a screening experiment with factorial design and response surface method (RSM) with central composite design (CCD) was used to optimize the electroless nickel plating on polyester fabric. A two-level full factorial design (FFD) was used to determine the effects of five factors, i. e. the concentrations of nickel sulfate, sodium hypophosphite and sodium citrate, pH and temperature of the plating solution on surface resistance of the electroless nickel plated fabric. It is found that the nickel sulfate concentration and temperature of the plating solution are the most significant variables affecting the surface resistance of electroless nickel plated fabric. The optimum operating condition is finally obtained by using a desirability function. The test for reliability for predicting response surface equations shows that these equations give an excellent fitting to the observed values. In addition, the deposit composition, surface morphology, crystal structure and electromagnetic interference (EMI) shielding effectiveness (SE) were studied. The EMI SE of the nickel plated polyester fabric obtained under the optimal condition is about 60 dB at the frequency ranging from 2 to 18 GHz.
